The Grade 2 Gulfstream Park Handicap, at $500,000, is the richest race of the day Saturday and is supported by the Grade 2, $200,000 Mac Diarmida and the Grade 3, $150,000 The Very One Stakes. But the sensational Songbird was entered in the Grade 3, $100,000 Santa Ysabel at Santa Anita, which certainly will command everyone’s attention. And the stakes are getting interesting again at Aqueduct, where the Grade 3, $400,000 Gotham is the main event.
